The BRS thermostat lets the cooling system get a head start on the temperature all of the car’s systems are creating. The thermostat may cause a check engine light on a street driven car but it doesn’t affect how the car runs. Because of this we only recommend running the thermostat on cars that are mostly driven on the track.
Now we are going to remove the OEM oil cooler.
We remove the hoses and unbolt it from the engine case.
The cooler is lifted free.
Here is the stock cooler size for the engine and PDK fluid comparted to the large BRS coolers. The difference in size is huge! The BRS units have more than twice the capacity and are about the same size as the units found on the 500 hp GT3RS or 991.2 Cup Cars.
To install the PDK cooler we removed this bracket.
